if you need 3/4 cups of beans for 7 servings. How many do you need if you want to make 35 servings
Answer:
3 3/4 cups
Step-by-step explanation:
We need 3/4 cups of beans for 7 servings, and we need to figure out how many cups we need for 35 servings. You'll notice that 7 times 5 is 35. We can multiply 3/4 by 5 to find the answer to our problem. This thought process looks somewhat like this:
[tex]\frac{\frac{3}{4} }{7} = \frac{x}{35}[/tex]
Notice that we can multiply 5 by 3/4 to find the value of x.
So, 3/4 times 5 is equal to 15/4, or 3 3/4. So, you need 3 3/4 cups of beans for 35 servings.
Hopefully this was helpful! If you have any more questions, let me know.

Hooke’s Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?
Answer:
Simple springs obey Hooke's Law. Hooke's Law states that the force on a spring is proportional to it's displacement from it's resting length:
F = -k*x
Where F is the force, x is how far the string is stretched or compressed, and k is a proportionality constant called the spring constant. The negative sign is because the spring resists stretching.
In this case, we can solve for k using the first case:
(100N) = -k * (5cm)
k = ???
And plug that answer in to find x in the second case:
(360N) = -k * x
This is a "Hooke's Law" problem: the restoring force required to compress or stretch a spring is proportional to the distance the spring is deformed. You can figure solve it by setting up a proportion equation and then using the algebraic tool of cross multiplication to solve for the unkown "stretch".
1) set up the proportion equation
100 = 360
5 x
2) cross multiply to get a linear equation
100x = 5*360
3) solve for x
100x = 1800
x = 18

Answer:
The law: F=kx
Therefore,
180N = k * 5cm
k = 180÷5= 36N per cm
Using the known constant with the law,
270=36*x
x= 270 ÷ 36 = 7.5cm

Answer:
14
Step-by-step explanation:
16-12
even: 12 14 16
You are 14!
8+8=16 and we are given that you are less than 16.
6+6=12 and we are given that you are more than 12.
So the number can be 13, 14, 15.
We are also given that the number is even.
And the only even number here is 14. And 14 has 2 digits.

Graham drove 42 1/3 miles in 1 1/3 hours. What is the unit rate for miles per hour? Use pencil and paper. Describe a situation in which the unit rate would be easier to work with than the given rate.
Answer:
Step-by-step explanation:
42+(1/3)
42*(3/3)+(1/3)
(126/3) + 1/3
126/3 + 1/3 = 127/3 miles
4/3 hours
(127/3)/4/3)
(127/3)*(3/4)
= 127/4 or 31.75 miles/hour
It would have been nicer if we were told Graham's distance after 1 hour (when he had travelled 31.75 miles).

5. Beni tiene el 40% de la edad de su hermano Aarón que tiene 24 años ¿Que edad tiene Beni?
Answer:
1. 27 liters
2. 125.8%
3. 3 years
4. 0.98%
5. 9.6 years
Step-by-step explanation:
1. (60%)(45) = 27 liters
2. Percentage of weight relative to ideal weight = (100%)(78/62) = 125.8%, rounded to nearest 10th of a percent.
3. (20%)(15) = 3 years
4. Assume that the beginning height is 2552 meters and the height increases 25 meters. Then, the percentage increase = (100%)(25/2552) = 0.98%, rounded to the nearest 100th of a percent.
5. Beni's age = (40%)(24) = 9.6 years

1: 12 * [tex]10^{9}[/tex]
We can easily tell this is the answer here as 12 is larger than 4. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.
2: 3 * [tex]10^{12}[/tex]
Same here, we can easily tell this is the answer here as 3 is larger than 1.5. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.
3: 6 * [tex]10^{5}[/tex]
This one is slightly more complicated than the other two, but still not to difficult when you know what you're doing.
A tip: 10 to the fourth power ([tex]10^{4}[/tex]) is 10,000. Aka, a 1 with four zeros!
For the first one, 20 has a zero, so we can take it and put it onto the 10th power. We know have:
2 * [tex]10^{5}[/tex] and 6 * [tex]10^{5}[/tex]
Using the same method as #1 and #2, we can tell that 6 * [tex]10^{5}[/tex] is the answer here!

A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function -4x+y=15, where x is time and y is velocity ion kilometers per hour. Use this function to determine when a certain particle will reach 30 km/hr.
Answer:
it will take the certain particle 15/4 (unit of time) to reach 30 km/hr
Input 30 as for y and solve the equation.
Step-by-step explanation:
Since y is kilometers per hour and the question is asking for how long it takes for a certain particle to reach 30 km/hr, you input 30 for y and solve for x.
-4x + y = 15
-4x + (30) = 15
subtract 30 from both sides
-4x = -15
divide -4 from both sides
x = 15/4
it will take the certain particle 15/4 (unit of time) to reach 30 km/hr

A standard deck of 52 playing cards is placed face down on a table how many cards must you draw from the deck to be certain that you will have a pair of the same value is to be determined.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
A card deck consists of 52 cards, and the deck has 4 number of cards of the same number but different families, which implies the number of 4 equivalents cards in the deck is 13 (Since 52 / 4).
According to the question number of the pair is to be determined that has the same value,
Total number of pairs = 2 * 13 = 26
Thus, the required number of picks that will be made for the same value is 26.

e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.

is 5(1/5^3) = 5(5^3)
Answer:
5(1/5^3) ≠ 5(5^3)
Step-by-step explanation:
5(1/5^3) = 5(5^3)
5/27 = 625
5(1/5^3) ≠ 5(5^3)
The sides aren't equal, so this equation is FALSE.
Answer:
Step-by-step explanation:
Short answer: No they are not the same.
5 * 1/5^3 = 1/5^2. One of the 5s in the denominator cancels out.
5^1 * 5^3 = 5^(1 + 3) = 5^4. Nothing cancels here. The powers add.

A deli sells sliced meat and cheese. One customer purchases 4 pounds of meat and 5 pounds of cheese for a total of $30.50. A sandwich shop owner comes in and purchases 11 pounds of meat and 14 pounds of cheese for $84.50. The system of equations below represents the situation.
4x + 5y = 30.50
11x + 14y = 84.50
The variable x represents the
.
The variable y represents the
.
The deli charges $
Answer:
The cost of 1 pound meat is $ 4.5 And cost of 1 pound of cheese is $ 2.5.
Step-by-step explanation:
Let the cost of 1 pound of meat be x
Let the cost of 1 pound of cheese be y
Cost of 4 pounds of meat = 4x
Cost of 5 pounds of cheese = 5y
Since we are given that one customer purchases 4 pounds of meat and 5 pounds of cheese for a total of $30.50.
So, equation becomes :
Cost of 11 pounds of meat = 11x
Cost of 14 pounds of cheese = 14y
Since we are given that a sandwich shop owner comes in and purchases 11 pounds of meat and 14 pounds of cheese for $84.50.
So, equation becomes :
Thus the system of equations are :
-1 (Red line)
-2 (Black line)
Solving these equations graphically we get the solution
x = $4.5
y = $2.5
Hence The cost of 1 pound meat is $ 4.5 And cost of 1 pound of cheese is $ 2.5.

Given PQ = 24
PS = 19
PR = 42
TQ = 10
m<PQR = 106°
m<QSR = 49°
m<PRS = 35°
find m<QRS, m<PQS, m<RPS and m<PSQ
The shape PQRS is a parallelogram
The measure of angle QRS is 70 degreesThe measure of angle PQS is 53 degreesThe measure of angle RPS is 35 degreesThe measure of angle PSQ is 53 degreesThe given parameters are:
[tex]\mathbf{\angle PQR = 106}[/tex]
[tex]\mathbf{\angle QSR = 49}[/tex]
[tex]\mathbf{\angle PRS = 35}[/tex]
(a) Find QRS
This is calculated as:
[tex]\mathbf{\angle QRS = 2 \times \angle PRS }[/tex]
So, we have:

Hence, the measure of angle PQS is 53 degrees
(c) Find RPS
This is calculated as:
[tex]\mathbf{\angle RPS = \angle PRQ }[/tex]
Where:
[tex]\mathbf{\angle PRQ = \angle PRS = 35}[/tex]
So, we have:
